To tZZ- whom it may concern.-

Be it known that I, SIGMUND V. HUBER, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented or discovered certain'new and useful Improvements in Rolling-Mills, of which improvements the following is a specification. v

The invention described herein relates to certain improvements in feed-tables for rolling-mills, whereby an article may be passed back and forth successively through different passes in the rolls and whereby each article may be succeeded by another article in quick succession, so that a series of three or five or more articles maybe in the process of reduction simultaneously by thev same set or stand of rolls.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a top plan view of a rolling-mill having my improved feed-table applied thereto. Fig. 2 is atop plan view of the rollers table, and Fig. 3 is a similar view of the catchers table. Fig. 4 is asectional elevation, the plane of section being indicated by the line IV IV, Fig. l, and passing through the second pass of the catchers table and the third pass of the rollers table. Fig. 5 is a sectional elevation,- the plane of section being indicated by the line VV, Fig. 2, and passing through the iirst pass of the rollers table.- Figs. 6, 7, and 8 are sectional elevations, the planes of section being indicated by the lines VI VI, VII VII, and VIII VIII, Fig. 2, and passing, respectively, through the second, fourth, and fifth passes of the rollers table. Fig. 9 is a plan View, the feed-rollers being removed to show the transfer mechanism. Fig. l() is a sectional elevation, the plane of section being indicated by the line X X, Fig. 2. Fig. 11 is a similar view, the plane of section being indicated by the line XI XI, Fig. 2. Fig. l2 is a transverse sectional elevation, the plane of section being indicated by the line XII XII, Fig. 2. Fig.

13 is a diagrammatic view showing the horizontal movements of articles through my improved mill.

In the practice of my invention I employ a three-high mill having passes so arranged that trough-like braces 6.

the first, third, and iifth passes will be be'- tween the lower and middle rolls and the second and fourth passes between the middle and upper rolls.

rollers and catchers tables. As these tables are similar'in construction except for a few minor features of construction, as will be hereinafter pointed out, the description will refer only to the rollers table.

Upon the sides of a suitable frame l are secured lthe bearings 2 for the feed-rollers 3, which extend entirely across .the frame 1 and are of a length approximately equal to the length of the reducing-rolls. As hereinafter described, the end and middle portions of these rollers are employed for feeding the article to be rolled into the rst, third, and fifth passes of the reducing-rolls, while portions intermediate of the end and middle por- On opposite sides of suchthreehigh mill are pla-'ced what I term the tions are employed for driving feed-rollers 4 and 5, which serve to feed the article into the second and fourth passes between the upper and middle rolls of the reducing-mill.

As shown in Figs. 4, 5, 6, 7, 8, and 11, a trough-like brace is arranged between the sides of the frame 1 in line with the feedrollers 3, which are partially inclosed by such In order to support the article being rolled intermediate of the rollers, aprons 7 are secured to the outturned flanges 6 along the upper edges of the brace 6, said aprons extending between the rollers at the ends thereof or portions in line with the first and fifth passes of the reducing-rolls, as shown in Figs. 5 and 8. Similar aprons l0 Iare arranged between the middle portions of rollers 3, forming a third pass, where said rollers are separated a sufcient distance to render an intermediate support unnecessary. In order to prevent the article being rolled from moving laterally o of the. rollers, side guides 8 are secured to the apron 7 by means of bolts, whose heads are arranged in under cut grooves 9, formed in the aprons 7, as shown in Figs. 1, 2, 3, 5, and 8. This construction or manner of supporting the side guides 8 permits of their adjustment trans-v versely of the aprons in accordance with the width of the article to be rolled. Vertical walls 11 and 12 are arranged upon the crossbraces 6 in line or approximately in line'with IOO ' clearly shown in Fig. 1 1.

the ends of the grooves forming the second and fourth passes in the reducing-rolls, as Between these walls are arranged the rollers 4 and 5, the journals of said rollers entering vertical grooves in the inner faces of the walls 11 and 12, said grooves being made of sufficient length to permit the rollers to rest upon the main rollers 3, whereby the rollers 4 and 5 are rotated. As shown in Figs. 6, 7, 9, and 11, side guides 13 and-14 are arranged upon the walls 11 and 12, said guides projecting up a sufficient height to insure the retention of the article being rolled in line with the passes 2 and 4 of the reducing-rolls. Integral with these guides Yare formed aprons 15, which extend each way from opposite sides of the rollers toward the adjacent rollers, so as to nearly bridge the spaces between such rollers.

It will be observed by reference to Figs. 4t G, 7, and Sthat the rollers are arranged coniparatively close together for the first, third, and fifth passes of the rollers table, but are farther apart in the second and fourth passes of the same table, the reason for such construction being that the first, third, and fifth passes of the rolleris table are what might be termed feed-passest'. c., the article is moved from such passes to the reducingrolls-while the second and fourth passes are receiving-passes, the article being forced into such passes by the reducing-rolls. In the catchers table these constructions are reversed, the second and fourth passes thereof being feed-passes, while the first, third, and fifth passes are receiving-passes.

In order to transfer the article being rolled from the second to the third and from the fourth to the fifth passes of the rollers table and from the first to the second and from the third to the fourth passes of the eatchers table, any suitable form or construction of transfer mechanism capable of vertical and lateral movement may he em ployed-sncl1,for example, as that shown in Figs. 4, 9, and 10. As clearly shown in Fig. 11,this transfer mechanism consists of heads 1G, provided with upwardly-projecting prongs 17, which are secured upon the upper end of a vertically-movable standard 13, which is arranged in snitable guides secured to a transverse beam of the frame 19. rlhe number of these lifting devices employed is dependent upon the length and thickness or rigidity of the article operated on, the longer and thinner the article the greater the number of lifters which should be employed. The frame 19 is made of such a length compared with the length of the feedtables as will accommodate the required number of lifters, and the transverse beams supporting thc guides 1S of the lifters are arranged at suitable intervals along the frame 19. At suitable intervals the side bars of the frame 19 are provided with laterally-projecting lugs 20, whose outer ends are suitably shaped to form bearings for the wheels 21, which are supported upon rails 22, arranged transversely of the feed-tables,helow the rollers 3 thereof. As shown in Figs. 1, 2, 3, and 9, the frame 19 is connected by rods 23 to crank-arms 24, secured upon ashaft 25, which preferably extends the entire length of the mill. This shaft 25 is rotated to shift the frame 19 through the mechanism described by means of a fluid-pressure engine 2G, having its piston-rod 27 connected by rods 28 to a crank-arm on the shaft 25. In order to effect the vertical movement of the standards 1S and the heads 16, shafts 29 are mounted in suitable bearings longitudinal of the frames 19, and on said shafts are seculed the pinions 30, adapted to intermesh with rack-bars 31 on the standards 1S. It is preferred to form the standards with a vertical slot and to arrange the rack-bars on the inner Walls thereof, as clearly shown in Figs. 9 and 10. As shown in Figs. 1, 2, and 4, these lifters are arranged to operate between adjacent feed-rollers 3, 4, and 5, and the heads 16 of such lifters are arranged a distance apart approximately equal to the distance between the second and fourth passes of the rollers table and the first and third passes of the catchers table. As will be seen by reference to Fig. 1, the lifting devices are arranged so as to transfer an article laterally from the second and fourth passes of the rollers table and downwardly to the IOO third passes and move it laterally to the second and fourth passes.

In order to rotate the shaft 29, whereby the lifters are raised and lowered, pinions 32 are secured upon the shafts 29, and with said pinions the rack-bar 33 intermeshes. This rackbar is connected to the piston 34 of the fiuidpressure cylinder 35,which is movably mounted in guides 3G, arranged upon a suitable foundation adjacent to the feed-tables. The fluid-pressure cylinder 35 is tied in suitable relation to the frame 19 so as to move therewith by means of rods 37, secured at their ends to the cylinder and frame 19, as clearly shown in Fig. 9.

In normal position of the transfer mechanism the heads 1G of the rollers table are in line with the feed-rollers. 4 and 5, forming the second and fourth passes of said table, and the heads 16 of the catcher-s table are in line with the first and third passes thereof. In operating my improved mill an article is placed on the ends of the feed-rollers 3 of the rollers table in line with the first pass of the reducing-rolls and is delivered by the latter to the first pass of the catchers table. The transfer mechanism is now operated to raise the article and shift it laterally onto the rollers 4, forming the second pass of the catchcrs table. 'lhe transfer mechanism is returned to normal position. A second article is placed in the first pass of the rollers table. As soon as the articles are deposited on the contimionsly-operating feed-rollers the first TIO article is fed into the second pass of the reducing-rolls and the second article into .the first pass of the reducing-rolls. The rolls deliver the first article into the second pass of the rollers table and the second article into the rst pass of the catchers table, respectively. The transfer mechanism is again operated to shift the first article to the third pass of the rollers table and the second article to the second pass of the eatchers table; After the transfer mechanism has been returned to normal position a third article is placed in the first pass of the rollers table. By the operation of the feed-rollers the first and third articles are fed into the third and first passes of the reducing rolls and the second article to the second pass of the reducing-rolls.

By the action of the rolls the third and first articles are fed into the first and third passes of the eatchers table and the second article into the second pass of the rollers table. The transfer mechanism is now operated to shift the first and third articles to the second and fourth passes of the catchers table and the second article to the third pass of the rollers table and then returned to normal position. A fourth article is then placed upon the first feed-pass of the rollers table, and by the action of the feed-rollers the first and third articles are fed to the fourth and second passes of the rollers table and the second and fourth articles to the third and first passes of the catchers table. The transfer mechanism is again operated so as to shift the first and third articles onto the fifth and third passes of the rollers table and the second and fourth articles onto the fourth and second passes of the catchers table. After the transfer mechanism has been returned to normal position a fth article is placed in the first pass of the rollers table. By the operation of the feed-rollers the first, third, and fifth articles are fed through the reducing-rolls into the fifth, third, and first passes of the catchers table, and the second and fourth articles are fed through the reducing-rolls into the fourth and second passes of the rollers table. The first article, which has now passed through the successive reducingpasses of the rolls, is removed by any suitable means from the fifth pass of the catchers table, and the transfer mechanism is operated to shift the second and fourth articles onto the fifth and third passes of the rollersthat after the first article has reached the fifth pass of the rollers table five articles will be in the course of reduction simultaneously by the mill, a new article being placed after each operation of the transfer mechanism in the first pass of the rollers table.

In order to facilitate the operation of the mill, a series of movable stops or abutments 38 are arranged at suitable intervals in the line of movement of articles in the first pass of the rollers table, one of said stops being located near the end of the rollers table adjacent to the reducing-rolls. These stops or abutment-s are preferably made in the form of arms keyed to shafts 39, which are mounted in suitable bearings 40, secured to the sides of the frame of the feed-table. In order to relieve shocks or jars incident to the impact of an article against the stops, the shafts 39 are removable longitudinally in their bearings, and springs 41 are interposed between one of the bearings and collars 42 on the shafts. In order to render the lifting of the stops or abutmcnts easy, counterweights 43 are attached to arms 44, projecting from the shafts 39 in a direction opposite to that of the arms 38. As will be readily understood, these stops or abutments render it possible to place a number of articles upon the portions of the rollers 3 forming the first pass of the rollers table and hold them in position to be fed into the reducing-rolls until after the operation of the transfer mechanism has been effected. As soon as the stop or abutment adjacent to the reducing-rolls has been lowered after the passage of an article into the reducing-rolls the other stops or abutments can be raised, permitting the forward movement of all articles resting on the feed-rollers one step or stage toward the reducing-rolls.

In order to insure the simultaneous operation of the transfer mechanism on each side of the reducing-rolls, the shafts 29 under each of the feed-tables are provided with pinions- 45 on their inner ends, adapted to intermesh with corresponding pinions 46 on the shaft 47, extending under the reducing-rolls, as clearly shown in Fig. 4.

I claim herein as my invention@- l. The combination of a three-high mill having three or more reducing-passes, three or more series of driven feed-rollers in line with said passes on each side of the mill, mechanism for driving two or more of said series of rollers on each side in one direction and one or more of the series on each side in an opposite direction, a mechanism on each side of the mill for transferring an article from one series of feed-rollers to the next adjacent series, and means for simultaneously operating both transfer mechanisms, substantially as set forth.
